Leverage virtual instrument controls on mobile phones and tablets to achieve remote measurement / control

One machine per person is an inevitable trend, and iPhones, Android phones and various other smart phones are becoming more and more common. The Information Technology Research and Analysis Agency (Gartner) pointed out that the global sales of smartphones in 2011 reached US $ 472 million, a 58% increase from 2010.

Mobile phone / tablet applications are gradually expanding

Smart phones are becoming more and more popular and are changing the way of life of human beings. For example, because they can carry a phone book with them, users do not have to remember phone numbers; they rarely need to ask for directions when driving, because smart phones have a global satellite positioning system (GPS) Navigation and map functions; with e-mail, text messages, and video calls, users can keep in touch with relatives and friends at any time. No matter where you are, you can find information at any time with a smartphone.

In addition, the influence of the tablet computer should not be underestimated. Forrester predicts that by 2013, tablet PC sales in the US will exceed desktop PCs. The positioning of the tablet computer is between the smartphone and the notebook computer, and like the smartphone, the tablet computer also has a network connection and a touch screen interface, and has the screen area of ​​the notebook computer.

As far as tablets are concerned, the first to be listed and popular is the Apple iPad, but Google, Microsoft, Samsung, HP, Amazon.com, RIM, etc. Big factories have also introduced their own devices and operating systems.

Tablets are no less influential than smartphones, so people no longer deal with daily affairs in the traditional way. With the iPad, users can download / read books, stream TV shows and read newspapers and magazines. As technology changes with each passing day, prices are getting lower and lower, and tablets are expected to dominate the future market.

People usually use smartphones and tablets as recreational devices to play games, stream videos, etc., but they are actually powerful engineering tools. In addition, people usually use desktop / notebook computers for simple tasks, such as surfing the Internet, word processing, playing games, etc., but this is also one of the most important tools for engineers to design, inspect, and manufacture products. It is used for various purposes such as measurement operations, storage of data, automated testing, execution of analysis and creation of reports.

Leverage virtual instrument control mobile phone and tablet to realize remote measurement / control

Use mobile phone / tablet to monitor machine status

Because smartphones and tablets are easy to carry and have connection functions, they have become a recreational device that people can't extricate themselves, but these features also bring another possibility for measurement and control applications-assist engineers in remote measurement The control system also provides a new platform suitable for portable measurement.

With the increasing number of smart phones, telecom operators are continuing to build base stations so that users can access the Internet anytime, anywhere. This type of base station architecture not only allows users to use e-mail, grasp the latest news reports and race conditions, but also helps engineers access measurement data everywhere.

As long as you have a smartphone and a tablet computer, engineers can remotely view and control the system through the Human-Machine Interface (HMI); in addition, you can also monitor data trends, continuously view historical data, and measure conditions Receive real-time alerts, remotely control applications or test processes.

Machine condition monitoring (Machine CondiTIon Monitoring, MCM) is a possible application method. The easiest way to assess the condition of the machine is by manual testing or even visual inspection. MCM continuously monitors machine performance and predicts the possible time to failure, repairs the machine at the most cost-effective time, and further automates the process of evaluating the state of the machine.

In many cases, the cost of machine failure is not just replacement parts, but the suspension of the machine will also bring additional cost burden, so it is necessary to notify the engineer as soon as possible to determine the cause of the failure; and smartphones and tablets can immediately issue failure notification, as long as Using a smartphone or tablet to view the on-site measurement status, engineers can even diagnose the cause of the fault remotely.
